Prime G1: Strange behavior after importing the backup

[BuSchu]

When I tried to add the Pragma instruction to the programs on my G1, the calculator froze. I revived it by resetting it and then restored the backup before the last firmware update. Now the calculator is behaving very strangely: When I open the information for the calculator in the Connectivity Kit, the calculator restarts and of course disappears from the Connectivity Kit. I have not yet found a way to restore the calculator to a normal state. Any idea how to make it?
